[Advances in the treatment of acute lymphoblastic leukemia in childhood: experience with intensive protocol treatments].
The authors analyzed a group of 64 children with acute lymphoblastic leukaemia (ALL) treated according to three protocols of different intensity. The best therapeutic results were obtained in children treated according to the most intensive protocol of the West German Multicentre Investigation BFM 83 which is graded as to its intensity with regard to the degree of risk of an adverse course. Successful remission in the entire group of patients was 93%, one third of the children developed during the investigation period a relapse of the basic disease. 12% of the children died during remission from complications of treatment. The surprising agreement of therapeutic results of different protocols after three years' complete remission is apparent from the fact that early relapses during the first two years of treatment, implying resistance to administered therapy, are at present the greatest problem of effective treatment which is not resolved even by the ever increasing intensity of treatment. In the conclusion the authors define the group of patients with a high risk of early relapse for whom new therapeutic procedures must be sought.
